The spouse of a patient who experiences delusions asks the nurse, “Are there any circumstances under which the treatment team is justified in violating the patient’s right to confidentiality?” What is the nurse’s best response?

Choice A reason: Histamine blockade, as in antipsychotics like olanzapine, promotes sedation, not weight loss. Weight gain is common due to histamine’s role in appetite regulation via hypothalamic signaling. Weight loss is not a typical side effect, making this response inaccurate for histamine-blocking medications.

Choice B reason: Histamine receptor blockade, common in medications like quetiapine, reduces wakefulness by inhibiting histamine’s alerting effects in the cortex. This causes drowsiness, a frequent side effect in psychiatric treatments, aligning with the pharmacological mechanism and making this the correct response.

Choice C reason: Insomnia is not typical with histamine blockade, which promotes sedation. Histamine enhances alertness; blocking it, as in antihistaminic antipsychotics, induces sleepiness, not wakefulness. This response contradicts the neuropharmacological effect, making it incorrect for expected side effects.

Choice D reason: Blood pressure increase is unrelated to histamine blockade. Histamine affects wakefulness and appetite, not vascular tone directly. Antihistaminic drugs may cause orthostatic hypotension via other receptors, not hypertension, making this response inaccurate for histamine-blocking medication effects.

Choice A reason: Interventions, like offering snacks, address identified problems (e.g., forgetting to eat) to meet nutritional needs. This action targets physiological deficits, potentially linked to cognitive impairments from low acetylcholine in dementia, ensuring adequate caloric intake to support brain function and overall health in the care plan.

Choice B reason: Planning/goals outline desired outcomes, not specific actions. Forgetting to eat, possibly due to frontal lobe dysfunction, requires goals like “maintain adequate nutrition.” Interventions, not goals, specify actions like offering snacks, making this section incorrect for the statement’s placement in the care plan.

Choice C reason: Assessment involves data collection, like observing eating patterns, not actions like offering snacks. Forgetting to eat may reflect cognitive deficits, but assessment identifies the problem, not solutions. This section precedes interventions, making it an incorrect location for the described statement.

Choice D reason: Diagnosis identifies problems, like “impaired nutrition” due to cognitive deficits, not specific actions. Offering snacks is an intervention to address the diagnosis, not the diagnosis itself. This section is incorrect for the statement, which belongs in the intervention phase of the care plan.
